installing a hydraulic hose to bypass the check valve, and then
pushing or towing the machine.
Important: Do not push or tow the machine faster than
3 to 4.8 km/h (2 to 3 mph) or for more than 0.4 km (1/4
mile), because internal transmission damage may occur.
The bypass valve must be open whenever you push or
tow the machine. Additionally, you need to install a
hydraulic hose to bypass the check valve whenever you
push or tow the machine in reverse.
If you need to push or tow your machine, you will likely need
to move it both forward and in reverse. To ensure that the
drive system does not become damaged from pushing or
towing, it is best to prepare the machine for both forward
and reverse pushing or towing.
Preparing the Machine for Pushing or
Towing in Reverse
Important: If you need to push or tow the machine
in reverse, you must first bypass the check valve in the
4-wheel-drive manifold.
The following Toro parts are needed to bypass the check
valve:
•
Toro Part No. 59-7410, diagnostic fitting
•
Toro Part No. 354-79, diagnostic-fitting cap
•
Toro Part No. 95-8843, hydraulic hose
•
Toro Part No. 95-0985, coupler fitting (2)
•
Toro Part No. 340-77, hydraulic fitting (2)
1. Install a diagnostic fitting in the unmarked port located
between ports M8 and P2 on the rear traction manifold
(Figure 43).

2. Connect a hydraulic hose between the diagnostic fitting
installed in the rear traction manifold and the reverse
traction pressure test port
Note: Use the hydraulic fittings and coupler fittings as
needed to install the hose.
1. Reverse traction pressure
test port
3. Rotate the bypass valve 90° (1/4 turn) in either
direction to open it and allow fluid to bypass internally
(Figure 45).
Note: Because the fluid bypasses the transmission,
you can move the machine slowly without damaging
the transmission.
Note the position of the valve when opening and
closing it.

4. When you are finished pushing or towing the machine,
remove the hydraulic hose that you installed.
5. Install the existing cap onto the reverse traction
pressure test port.
